Our value proposition includes Manufacturing, Systems Integration, Turnkey Project Implementation (SITIC) and Maintenance Depot; for SDR, SATCOM, Cellular and Terrestrial Broadband radios.
Digital Mobile Radio - DMR
Digital Mobile Radio (DMR) works in VHF and UHF bands. The Radio is designed, developed and manufactured under MAKE IN INDIA Programme. It Supports limited open Digital Mobile Radio standard defined in the European Telecommunications Standards Institute (ETSI) Standard TS 102 361 parts 1–4 and used in commercial products around the world. DMR, uses proprietary AMBE+2 vocoder and two-slot TDMA in a 12.5 kHz channel. The Radio offers both voice and data communications and interfacing to external networks. Voice communications offer features as call alert, emergency call, remote monitoring, silent worker, Push-to-Talk ID, radio check, all call, stunning etc. The Radio also offers Greater call capacity, high reliability, Security features, better call quality, Privacy features, longer battery life, increased spectrum efficiency.
Key Features
- Comply to ETSI TS 102 361 parts 1–4 standards For Air Interface Protocol DMR Voice and Generic Services, DMR Data Protocol, DMR Trunking Protocol and DMR General System Design
- 4-FSK modulation (constant envelope)
- 2-slot TDMA Channel. Built around a 30 ms Slot structure
- 6.25 kHz channel equivalence without the need to split the channel in the frequency domain
- 50% duty cycle slot structure allows forward and reverse transmission on a time division basis
- Possibility of two calls on the same radio channel
- Battery save option
- 9.6 kbps gross bit rate
- Transmission can be used either for voice, data or generic signalling

High-Capacity Radio Relay (HCRR)
High Capacity Radio Relay Radio (HCRR) Equipment is designed and developed under the MAKE IN INDIA Programme. It operates in frequency Band -IV (4.4 GHz to 5.0 GHz) capable of Full-Duplex Data transfer up to 100 Mbps. Radio can be deployed for Point to Point (P2P) communication link using Narrow Beam Antennas at Data rates 2, 8, 34 & 100 Mbps, for a communication range of 20 KM in Fixed Frequency mode. Radio supports Data rates of 2 and 8 Mbps, for a distance of 20KM in single hop and 35km in repeater mode during Frequency Hopping mode. The Radio can also be deployed for Point to Multi Point (PTMP) Communication Link using Sector antennas, over a distance of 15 KM at 8 Mbps aggregated user data rate in Fixed Frequency mode.
